MK-7655 is a ?-lactamase inhibitor that inhibits hydrolysis of nitrocefin by KPC-2 ?-lactamase from K. pneumoniae and AmpC ?-lactamase from P. aeruginosa (IC50s = 210 and 465 nM, respectively).{41428} It restores imipenem-susceptibility in imipenem-resistant K. pneumoniae and P. aeruginosa when used at concentrations of 12.5 and 4.7 ?M, respectively. MK-7655 also restores imipenem sensitivity to resistant clinical isolates of P. aeruginosa and K. pneumoniae (MIC50s = 0.25-2 and 8-16 ?M in the presence and absence of MK-7655, respectively), but not A. baumannii.{41429} In vivo, MK-7655 (48.9 mg/kg per day) produces a bacteriostatic effect in mouse thigh models of K. pneumoniae and P. aeruginosa infection when administered with imipenem (Item No. 16039) and cilastatin (Item No. 23511).{41430}
